I know the gzip works because I've tested it with an ASP.NET application. Has anyone else encountered this problem?

  Re: IIS7 PHP FastCGI and gzip compression Reply Contact The first one indicates that the request had no Accept-Encoding header and the second one indicates that the request came via a forward proxy (had a via header) - you should be able to verify that is the case by looking at the content of the GENERAL_REQUEST_HEADERS event earlier in the trace log - for the second one, you can change the behavior by setting noCompressionForProxies to false in the httpCompression section (%windir%\system32\inetsrv\appcmd set config -section:system.webServer/httpCompression -noCompressionForProxies:false) Anil Ruia Senior Software Design Engineer IIS Core Server
